In the drawings forming part of this specof cap screws 21 which pass through the said ification: male die members. The members 19 as Figure 1' is a plan View of my invention shown in Figure 3 are spaced from one an wi'th portions cut away. other and are, arranged in parallel rows. 4 Figure s a longitudinal sectional View The construction of the lower mold memtaken on the line 2 2 of Figure 1. her C is as follows: This member consists Figure 3 is a sectional view taken on the primarily of a rectangular frame 22 which line 33 of" Figure 2. is formed with a rectangular opening 23 in.

50 2, with the upper mold member removed sides 2% and 25 and ends 26 and 27 Within Figure 4 is a plan view similar to Figure the center of the same, said frame having the opening 23 of the frame 22 is positioned three female die members 28, 29 and 30, which are arranged adjacent one another and are held clamped between the sides 24 and 25 of the frame 22 b means of cap screws 32 engaging the en s thereof. These cap screws, as will be noted in Figure 4, are recessed into the sides 24 and 25 of the frame 22 so that the same lie flush with the outer surface of said frame.

Each of the female die members 28, 29 and 30 is chilled casting and is formed with a plurality of wedge-shaped pockets 33 which are of the same general formation as the wedge-shaped die member 19, excepting that the same have the arcuated ends thereof open. It will be further noted that the upper surface indicated at 34 of the female die members 28, 29 and 30 is curved to fit thearcuated furrows 16, 17 and 18 of the bed 15 so that when the mold members B and C are clamped together, a tight connection along the upper surface of said mold is provided.

36 which issuerearwardly from the bed 15.

and frame member 22 and which are hingedly connected at their ends 37 by means of a bolt 38. At the forward end of the mold member I provide two semi-cylindrical struts 39 and 40 which issue outwardly from the forward end of the bed 15 and the front end 26 of the frame 22, said struts being arranged in axial'alignment with the arms 35 and 36. The entire mold is held supported in two semicircular notches 41- and 42 formed at the centers of the walls 10 and 11 of the supporting member A at the upper portions thereof as can be seen in Figure 2. The arms 35 and 36 rest in the slot 41 while the struts 39 and 40 are provided with an annular groove 43 extending around the same and rest in the slot 42. By this means the entire mold may be rotated as a unit in notches 41 and 42 so that either of the surfaces thereof may be successively exposed to the heat generated by the burner 14 as desired. For gulding the forward end of the mold members together, I provide a dowel pin 44 which is attached tothe diametrical face of the strut 40 and co-operates with a registering hole 45 in the strut 39 in the usual manner.

F or manipulating the device a pair of handles 47 and 48 are employed which are rigidly secured to the struts 39 and 40 and.

which extend outwardly from the mold proper. By means of the handles the mold members B and C may be operated as desired so as to open or close the mold. To facilitate manipulation of the mold in the opening or closing of the same, I provide an arm 49 which is bolted to the rearward end of the bed 15 by means of bolts 50. This arm has attached to it a counter weight 51 which is adjustabl held thereon by means of a screw 52. In this manner the handle 47 may be easily raised to open the mold and the mold member B remains stationary when left in a vertical position.

The exact construction of the die members employed in my invention can be seen in Figure 2 and in detail in Figure 5. Each of the male die members 19 is formed with the upper arcuated ends of the same slightly bowed outwardly as indicated at 53. At the same time the sides of the die member taper toward the point as can best be seen in Figure 3 making the extreme point 54 of the die member at its upper end. This permits of readily withdrawing the receptacles from the mold and of separating the die members.-

As will be noted in Figure 5, the formation of pockets 33 in the female die members is similar in shape to the male die members, the walls of said pockets being spaced from i the sides of said male die members to form the space which the batter occupies. It will be further noted that the walls of the female diemembers are formed with corrugations indicated at 56 which extend vertically relative to the mold. These corrugations assist in causing the chocolate or icing whenever the same is used to adhere to the, surface of the receptacles.

' For forcing and locking the handles 47 and 48 together, I employ a device shown in' Figure 2. This device consists of a bar 57 which extends across both of said handles and which is rotatably and slidably mounted upon the upper handle 47 by means of-an eye bolt 58 secured thereto. At the lower end of said bar is pivotally' attached at 59 an eccentric disc 60 adapted to ride against the lower handle 48. This disc is formed with an annular groove 61 which engages the handle 48 and has a lever 62 issuing outwardly from the same by means of which said disc may be operated. Itcan readily be comprehended that when the handles 47 and 48 are brought together that the bar 57 may be swung to bring disc 60 below the handle 48 when the lever 62 has been thrown forwardly.

Upon the raising of said lever, the eccentric disc 60 is caused to bear against the lower handle 48 and to force said handles together to rigidly clamp the mold structure in place.

\Vhen so clamped, the mold may be readily rotated in the notches 41 and 42 as a unit to successively expose both sides of the same to the action of the burner 14.

In using my invention, the mold member C is placed downwardly with the pockets 33 positioned as shown in Figure 3. The member B is then swung upwardly on the pivot 38 so that the lower mold member C is exposed as shown in Figure 4. In this position the batter, preferably of a freely flowing consistency, is poured over the mold member C so that the same runs down into all of the pockets 33. After closing the mold member B and clamping the same together, the mold is heated by means of the burner 14 on both sides thereof until the receptacle is suitably baked. When the mold is then opened, the receptacles may be easily removed therefrom, after which the same are trimmed and coated as before described if desired.

The advantages of my invention are manifest. A simple construction is provided in which pie-shaped receptacles may be readily baked in large quantities. By forming the female die member of a chilled casting the molds may be placed close enough together so that a great number may be secured in a relatively small space, thereby greatly increasing the capacity of the machine and reducing the cost of manufacture of the receptacles. By supporting the female die members within the rectangular frame, the same may be independently adjusted to fit the male die members and individual sections may be removed and replaced as desired. The arcuated furrows provided on the bed support the male die members so that the same are arranged in uniform formation.

In accordance with the patent statutes, I have described my invention, illustrating the best embodiment thereof, but I desire to have it understood that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

I claim:

1. A receptacle forming machine comprising a bed, a plurality of arcuated furrows formed thereon, a plurality of male die members having curved ends adapted to lie in said furrows, and female die members co-operating with said male die members.

2. A receptacle forming machine comprising a bed, a plurality of arcuated furrows formed thereon, a plurality of male die members having curved ends adapted to lie in said furrows, female die members adapted to co-operate with said male die members, and curved ends formed on said female die members for engaging the arcuated furrows of said bed.

3. A receptacle forming machine comprising a bed, a plurality of arcuated furrows formed thereon, a plurality of male die mem-' bers having curved ends adapted to lie in said furrows, said male die members being spaced from one another, and female die members having a plurality of pockets adapted to co-operate with said male die members.

4. A receptacle mold comprising, a female die member of sector shape, the walls of said die member being bowed outwardly in the center thereof, and a male die member co-operating therewith.

5. A receptacle forming machine comprising, a bed, a die member having a curved end supported by said bed, said bed being provided with means adapted to receive the curved end of said die member, and a die member having a pocket adapted to receive the first mentioned die member.
